Minimserver 2 installation on QNAP TS419PII

[paulkwan]

i just install MinimServer 2 on a QNAP 219p+, using the ARM v5 package, and install the JRE_ARM by mistake ^^:
then uninstall JRE_ARM and install the JRE successfully
but i can only get this error : Unexpected exception java.lang.NullPointerException on config status and watch.
check the log and find it is error on start, no media scanning activity.
tried a few reboot and reinstall JRE, still not work, any tips ?
